Abstract
In order to provide theoretical basis for evaluations on ecological function rehabilitation and vegetation development, the herbaceous diversity of the Pinus tabulaeformis Artificial Forest, especially the relationship between biodiversity of herbaceous species and stand density were analyzed in western Liaoning province. The results show that only at suitable density the biodiversity were higher and that the 7 factors relative to the herbaceous biodiversity of P. tabulaeformis forests are all important, and among them 5 factors, i. e. the elevation, slope gradient, slope position, density and slope direction are especially more important.关键词
